Umm, if someone sold me "rubbing alcohol", I'd wonder what was in it.
We have a similar issue here (UK) with "surgical spirit" -- goodness
only knows what's in that. But if someone sold me "70% isopropyl
alcohol" I'd expect it to be an azeotropic micture of IPA and water,
and would be entitled to sue him (or have Trading Standards prosecute)
if it contained anything else.
